Cryopreservation

Sperm Freezing

Cryopreservation is a technique, which is used to preserve sperm in liquid nitrogen at -196°C. We can preserve ejaculated as well as testicular sperm. Sperm can also be frozen in advance of the day of egg collection if you anticipate difficulties with semen collection or if the male partner is out of town. However, we only offer sperm cryopreservation to couples undergoing IVF/IUI cycles at our centre.

Embryos Freezing

Cryopreservation is a technique, which is used to preserve good quality supernumerary embryos in liquid nitrogen at -196°C. These embryos can be used in subsequent cycles in case of cycle failure or if subsequent pregnancies are desired. By transferring these frozen thawed embryos, you can have extra attempts at achieving a pregnancy without undergoing a full stimulation cycle.

Note that only good quality embryos are used for freezing since only strong embryos can withstand the strain of freezing.

In a freezing cycle, embryos are thawed and transferred into the uterus in the same way as a normal embryo transfer procedure. Transfer of these embryos is usually carried out in a hormone replacement cycle, but can also be performed in a natural cycle in which fertility drugs have not been used. One of the other advantages associated with this process is the low cost involved since expensive fertility drugs are not required. At our Centre with a robust Cryopreservation program, we are able to offer equal if not better pregnancy rates in our frozen embryo transferred cycles as compared to fresh cycles.

Egg donation

We offer egg donation program at our centre for women who are unable to produce their own eggs. The donors undergo a screening process before they are recruited for an IVF cycle. We accept only known or altruistic donors.
